IMPROVEMENT Iii-,suitrit-Nutte -Be it .known thatI, Da N P EASE, of thetown of Floyd, in the county of Oneida, Vand State of New York,

'have invented a. new and useful Improvement in the smut-Milli and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation-of the s'a-me, referenceAbeing had to the annexed drawings, Vmaking a part ofthis-speciiication, in which- Figure 1 is anexternal perspective view ofthe entire machine, including the improvement.

Figure@ ,is a perspective view ofthe lower part of the mill, partlyturned round', showing the improvement at a, as it is connected iviththe mill, in the rear. Y

Figure 3 is a view of the part composing the improvement taken ed',and-shown separately.

Figure 4 is a vertical cross-section, `in outline, of the whole mill,including the improvement, and

Figure 5 is the essential part of the improvement, shown by a top view,and exhibits its connection with the, circular figure of the cylindercase, which contains the revolving part of the mill.

The object of the Aimprovement: is to furnish the means of spreading thegrain as it passes from the mill,

iii order to a'ord greater facility for the air which passes up throughit to separate and 'carry oif the foul stuff.. i It is designed to beused in connection with" my smut-mill, patented by me on the 22dday ofSeptember, 1868,

but may be attached to and used in connection with any other smut-millor machine.

The-force of thei revolving cylinder, in the smut-mill, drawing in avolume of air, blows out, in a lateral direction,`most of the dust,chaff, and light stuff, and discharges it at A, fig. 1, and the` grainbeing brushed and scoured by the action of the cylinder, passes rapidlytowards the discharge below, but still carries with it 'more or lesslight grain, chess, and other `foulstuti'l This is acted upon with aview to its separation from the grain by the swift current of air whichit meets near the discharge at the mouth 'of.the air conductor f. But

in order that the sir should act advantageously for this purpose ,thevolume of grain thus' descending Ato the discharge should be well spreadand divided in the passage.l v This, as smut-millshave been heretoforeconstructed, is not sufiiciently provided for; and my invention providesa simple and e'ective spreader for this purpose, scattemgand dividingthis volume of grain in such a manner as to permitthe swift current ofair that passes up through it to carry oil' all the remaining dust,light grain, chess, and other impurities, leaving the grain bettercleansed than has heretofore been done.` 'l

In the operation of the smut-mill the uncleaned grain is introduced tothe top of the cylinder through a spout, not shown in the drawings, butis situated near the shaftof .the pulley b, fig. 1. It is cleansed bythe action of a revolving metal cylinder, the stationary base of whichis seen at c, fig. 2. When sufficiently scoured, itpasses off from thecylinder chamber through a. passage indicated by Ythe arrows die, iig.4, and

entering the air conductorf, near its `Jmouth, is discharged at gf Onentering the conductor f it meetsa stili current of air passing up theconductor', and which is drawn in by the swift operation of thefan-blower, located on the cylinder-shaft underneath the machine [I hecircular easement of this fanfblouer is partially seen at k,

figs. 1 and 2. -This current of air carries the light impurities up theconductor-f, and over into the upright part l, according to the courseindicated by the arrows n op, fig. 4. My improvement for spreading thegrain is located in thepassage for the grain leading from the bottom 'orlovver part of the cylinder-chamber to the conductorf, and, forms thecommencement or upper part of this passage. The passage within thespreader extends from k to l, iig. 2, and is of a length correspondingto the width of the flat conductor j', iig. 1. This passage iscontracted in breadth as it proceeds 4to the end l, so that the last-ofthe partitions m, figs. 2 and' 3, almost closes across The shape of thewholepassage is seen at k, fig. 2nhere 2' is the bottom, and is on alevel with the base of the' cylinder C. 3 is the farther side, and 4 aprojecting portion of the opposite side.v

The parts composing the improvement are more distinctly shown in iig. 3,which is the attachment seenat k l,

iig. 2, taken oil' and shown separately.Y This new attachment I calla'spreader. The scoured grain in passing from thecylinder-chamber to thespreader, being driven with great force byl the swift action of' thecylinder,

strikes the partitions m, figs. 2 and 3. These partitions are placedvertically against the farther side of the passage, and extend forwardover thefdrip4 or inclined base below, but'do notreach quite down toit;nor do they extend forward fully across the passage, but stop a littleshort of it, and nearl the edge of the bottom 2, iig. 2, and leave thefront portion ofthe passage unobstructed. A portion of the passing grainstrikes each of these partitions, and as it stiikes immediately falls tothe drip below, which -leuds irito th'e conductorf, fig. 1. Thisoperation divides'the'volurne of grain, and occasions it to fall in avdivided sheet to thel mo nth of the con- Meer "ddctorf, whereit meetsthe swift current of air, ivhich carries up the lconductor the lightgrain, chess,- and other impurities, while the cleansed grain isdischarged at the mouth g ofthe conductor. yIn fig. 1, the spreader isseen projc'ctingat GH,Where it is covered by its easement. Gcorresponds. to the cover G in gs..2und 3,

and H is the cover of the portion ofthe spreader on the opposite side ofregulating slide I. This-reglilatin'g slide is an important agent. It isoperatedbymans of the hnnd-`le`ver J.- It is hungon the fnlcrumpin-w,and

shuts de'n betweenthe covers G and H. l"If the grainfalls too muchbetween the partitions 'nearestto k,.`

fig. 3, theslide I is let down to cut it oil" and send it farthertowards the end Z of the spreader. If toolittle is dropped at the end k,the slide is raised. f This slide, Ain figs. 2 and 3, ieshbwnJ raisedout'V of the way to show the partitions m and the spacesbetvreen them."In a mil-i of full size, these partitions arenbout tivo'and n. halfinches apart. The passage forth'e grain from the spreader to theconducter f is angular in its course, as indicated by the arrows d c,iig. 4, .which also .assists inv spreading the voluuie'of grain as-itpasses down. Figi' presents a top view of the spreader, as connected`with the circle-kof the cylinder case, .and with the'covers-G und H,tig. 3, taken o', so .este show theTup-per edges of the parts. Irithisfigure, N is the upperedge of a y, l

narrow i'leifriblehoard or-plate, lying diagonally from end Ato' endofthe passage,y as shdwn in theV figure, and is Vacted upon" by the,thumb-screw R."V It is braced atwnch end, but being vflexible. iscapable of beingv pressed inward in its centre by the seremtojnarrowthe; passage, and -to 4regulate the passage ofthe grain, and promote,nu: equal spreading of its volume. As Athe' impurities thus carried Aupthe lair."conductor f, according tothe course of 'the arrows n 011 fig.v4, include lightgrain, chess, and other lighter material, theniill'isdesigned tb divide theseI materialmand separating' theglighter'andentirely valueless materials from the heavier portion, the formerfiscarried over into the verticnlfportion z', fig. 1, of the conductor,andxis discharged at the month ofthe' fan-case at t, iig. 2, while thelatter, 'containing material 4of some value, falls upon the inclinedbase 'u of tlie conv ductor, fig. 4, and sliding down this deelivity;isdischarged at the spout V, tigrl. For the puinose of impro-ving' thisseparation, I have madea longitudinal eper'xinglin thenvnder side, nearthe lower end of this declivitj'l-and fixed therein a fine screenof'wire cloth,',nt .'w,`lg 4,'for a'lmitting a current'of. airimmediately under and quite across this broad conductor. Underneaththis/inclined plane,and at the angle formed by it and the upright part'of the conductor, is an enclosure,l te, figs'. 1 and 4.'. This'enclosure is divided into two apartments by the partition i y, iig. 4.In the upper part f this enclosure,and opposite the aforesaid wirescreen, is an opening, Z, for the admission of a current of air to passup through this wire screen, and thence through the aforesaid sheetoi'coarse= material as it descends, assisting `to carryover such dust andlight stuff asmay still'be mingled therewithfinto the conductor z. .Tothis 'opening Z is aixed the slide vgate L, to .regulatethe vamount ofair to be admitted. Ihus the dusty and light material are carried1 overinto theeonductoi' z', and the heavier portion is dischai-ged'at thespout V, fig. 1, as before mentioned.v In the lower part of theenclosure x is another opening, to `which is aliixed a vibrating gute,vS, whiehis actuated by the entering current of air, which tends tocloseit. It is opened 4against the force of this current bytheaccumulating weigh'tof the descending material, which'passes thence intothe spout V, and is discharged. T, fig. 1,'is another wire screen,inserted in the back sideof-thwspreider. This screen is also seen' at T,tige.l 2 and'3. It is intended as a vent for theescape of-the airdriv'e/n 4til1rdi`igl1 thespreuder with the passing grain, to preventthis current ofar from affecting the strength of thecurrent drawn intothe conductor-f by the action of the .an-blower. i D, iig. -1, is aswinging-valve gate in the'outside of the conductor z'. ,The strongdraught, occasionedby thefswiit action'of tle fan-blower,tends to openthis valve; and the weight E, hnngnpon a lever outside of the valve,keepsit closed.with a. strength'correspnding te the'length ef leverage.used in hanging the'vreightf.` If'the current of air in the conductor fis too strong, and carries up the. grain, less leverage is given to the,weight E, allow'ingthe gate D to open, letting in a counter-current ofair to modify'thestrength ofthecurrent in the lconductor f. This;.device is not claimed as new. ,i I d. V n
